What is the path for the large belt.. to put on.

Can any one tell me the path of putting the large belt back on?
1998 Lumina LTZ 3800 Series 2 (code K) engeine.
There are 3 wheels on the bottom.. .. one the middle one and small one above that (the tensions one).. and then the small one on very top.
Starting from Bottom right to the middle one ... to the one above that and then the top.. how does the belt go on... Under the wheel... over the wheel?? If someone could give me directions I could put it back on. The wheel on the tension first I have to replace.. it is worn out. Almost comming off. All I have to do is get the large nut off...LOL.
Thanks,,,

Did you look to see if your belt routing guide is still under the hood. There should be a sticker near the radiator or strut tower showing you proper routing. IF not, go to a decent Auto parts store, and they should have a routing guide in their catalog rack or in their computer.

Thank you.. you were very helpful.... it was under the hood! Helped me Bunches! One of the wheels broke. Then one on the tensioner so belt came of and I didn't know how to get it back on... It is all fixed now!
